What iSEMcon does
iSEMcon GmbH is a German manufacturer of measurement microphones and acoustic sensors, founded in 2010 and headquartered in Viernheim, Germany, with a US sales subsidiary (iSEMcon LLC) in Sylvania, Ohio. The company designs and supplies electret microphone capsules built around sputtered mylar diaphragms with integrated FET preamp stages, alongside ICP/IEPE-compatible microphones, sound calibrators, and the OPS outdoor measurement system. Its flagship EMX-7150 handles SPL up to ~145 dB with THD under 3% and accepts a wide 12V–52V phantom-power range, while products are individually calibrated against B&K 4133/4191 reference microphones for measurement traceability. The portfolio spans the EMX, iSEMic, and EMM series, targeting acoustic measurement professionals such as FOH and system engineers who require SPL monitoring and legal-limit compliance.
The company operates a direct-to-consumer go-to-market model: hardware is sold through the isemcon.net storefront, while the my.iSEMcon customer portal (my.isemcon.com) handles product registration — activating a 5-year extended warranty (vs. standard 2 years) — calibration file downloads, support tickets, and lost/stolen product tracking. Revenue streams comprise hardware sales, calibration services tied to registered units, and the extended-warranty registration. The dBlimits.com reference tool covers legal SPL limits across multiple countries (Germany, UK, France, Netherlands, Belgium, Italy, Austria, Sweden, Norway, Switzerland, USA, and WHO), supporting customer use cases in regulated venues and events. iSEMcon is structured as a privately held partnership owned by CEO Wolfgang Frank (Dipl.Ing.(FH)) and partner Sabine Frank, with no disclosed outside investment and a headcount reported in the 1–10 range.
